Abstract

The invention relates to a method for treating a monomer, pre-polymer, polymer or a corresponding mixture, in particular for producing a dope for producing a polymer fiber, in particular a p-aramide fiber, in which the monomer, pre-polymer, polymer, additives or a corresponding mixture is admixed with a solvent, blended, fused, homogenized and/or degassed and then discharged, which takes place at least partially in a reactor (7), is to force-feed the monomer, pre-polymer, polymer or a corresponding mixture into the reactor (7) using a force-feed device (4).
